AIR DISTRIBUT ER OR SPREADER.

SPECIFICATION forming part of Letters Patent No. 603,105, dated April26, 1898.

Application filed October 11, 1897- To all whom it may concern.-

Be it known that I, JOSEPH J AUCH, of Meriden, in the county of NewHaven and State of Connecticut, have invented a new Improvement in AirDistributers or Spreaders; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in- 1 Figure 1, aview in side elevation of an airdistributer or spreader constructed in accordance with my invention;Fig. 2, a view thereof in vertical central section; Fig. 3, a viewthereof with the deflector and retainingscrew removed; Fig. 4, adetached plan view of the deflector; Fig. 5, a reverse plan viewthereof; Fig. 6, a view of the air-distributor in transverse section onthe line a b of Fig. l and looking toward the deflector; Fig. 7, asimilar View of the air-distributor on the line 0 d of Fig. 1 andshowing the supporting and centering arms; Fig. 8, a detached view ofthe retaining-screw; Fig. 9, a detached plan view of the washer-likecurrent-breaker.

My invention relates to an improvement in air distributers or spreadersfor Argand or central-draft lamps, the object being to produce a simple,compact, and highly-eflective device.

\Vith these ends in view my invention consists in an air distributer orspreader having certain details of construction, as will be hereinafterdescribed, and pointed out in the claims.

In carrying out my invention I employ an inverted cup -1ike deflector,by preference formed from a single piece of sheet metal and comprising,as shown, a cylindrical body A and a horizontal flange A, the upperportion of the said body being formed, as shown, with two circular rowsof perforations a, and the flange beingimperforate or solid. Imay,however, choose to employ only one row of perforations, from which Ifind excellent results are obtained. The said deflector issupported upona standard consisting of an air-tube B, to which it is firmly secured bymeans of a retaining-screw G, which passes downward Serial No. 654,811-(iio model.)

through an opening A formed in the center of the body A of thedeflector, and into the internally-tln'eaded extreme upper end of thesaid air-tube B. The upper end of the said air-tube is formed withair-ports B, which are in the form of rectangular openings, as shown,but which may consist merely of round perforations, if preferred. Theseperforations are located just below the screw-threads formed in the tubefor coaction with the screw C. Preferably, although not necessarily, Ialso employ a washer-like current-breaker D, which is made independentof and mounted upon the air-tube B at apoint just below the air-ports B,formed therein. At its lower end the tube is supported within threeradially-arranged supporting arms E, which support and center the devicewithin the airtube of a lamp; but the particular means for supportingand centering the air-tube may be changed as desired, and constitute nopart of my present invention. It willbe observed that the air-tube isenough smaller in external diameter than the internal diameter of thebody of the deflector to form an annular air-chamber F within thedeflector, the said chamber opening downward around the tube and beingfree for the access of air into it from a point below the said flange A.

In using my improved device air enters the deflector through the openlower end of the annular air-chamber F and is jetted outward through theperforations a, formed in the upper portion of the cylindrical body ofthe deflector. A smaller quantity of air also enters the lower end ofthe air-tube and rises and emerges through the air-ports 13 thereof intothe annular passage E, from which it is jetted outward through theperforations a. Air is thus supplied to the interior of the deflectorthrough the annular chamber F, which opens downward, and through theair-tube.

The function of the washer-like currentbreaker D is to guard the lowerend of the air-chamber F against the entrance into it of air-currents oftoo much strength, whereby the action of the air distributor or spreaderis made even and protected against drafts. I am not, as aforesaid,obliged to employ the said current-breaker, but I flnd its use secures asuperior action of the device.

It is to be noted that the exterior surfaces of any part of thedeflector are not relied upon to give direction to the air, but that thesame is jettedoutward in such a manner as to supply air to and assist inshaping the form of the flame by the tension which it acquires in beingheated within the deflector and tube. I do not consider it imperative totake air through the air-tube as well as through the annular passage,but prefer to do so; nor do I consider it necessary to form the cup inthe exact manner shown, but in any form which it may assume it will beconstructed with an imperforate flange with a perforate body andarranged to take air from beneath into its body and jet the same outwardthrough perforations formed in the upper portion thereof. If desired,the deflector itself may be made in more than one piece, and instead ofsecuring it to the standard by means of a screw it may be riveted,soldered, or otherwise attached thereto.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an air distributer 'or spreader, the combination with an invertedcup-like deflector having a perforated body and an imperforate flange,ofan airtube upon which the deflectoris supported ,which is enough smallerin external diameter than the internal diameter of the body of thedeflector to form a downwardly-opening air-passage, and which is formedat its upper end with air-ports from which air taken at its lower endissues into the interior of the body of the deflector from which it isjetted through the perforations therein.

2. In an air distributer or spreader, the combination with an invertedcup-like deflector having a perforated body and an imperforate flange,of an air-tube upon which the said deflector is supported, and which isprovided at its upper end with air-ports which open into an annulardownwardly-opening air-passage formed between the upper end of the tubeand the the body of the deflector; and a screw passing through the bodyof the deflector and downward into the upper end of the tube forsecuring the deflector thereto.

3. In an air distributer or spreader, the combination with an invertedcup-like deflector having a perforated body formed with acentrally-arranged opening, and with an imperforate annular flangeextending outwardly from its lower edge, of a tube having its upper endinternally threaded, supporting the said deflector, and made smaller inexternal diameter than the internal diameter of the body of thedeflector so as to form a downwardly opening annular passage throughwhich air rises into the said body from which it is jetted through theperforations therein, and a retaining screw passing downward through thecentral opening in the body of the deflector, and entering theinternally-threaded upper end of the said tube to which it secures thedeflector.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOSEPH JAUCH.
